Functioning forest Loss of woodland conditions


Spring 2013 – extensive browning on DF:• On last year’s late growth;• Climatic?


Restocking & start the recovery of forest ecosystem:1.

Species – WRC 50%, DF 30%, SS 10%, NS 10% @ 3000 SPH;Natural infill of birch; Kill larch regeneration to at least Oct 15;

2. Design –

Spruce on clay; SS windward edges; WRC in lower light; 4‐

line mix;3.

Protection –

intense deer culling;4.

Claim FC grant – WRG & P. ramorum supplement: £1500/ha

Short term aim – obtain canopy closure asap


Start with what we know we don’t want!1.

Avoid large tracts of even‐aged monoculture;2.

Avoid highly stocked, closed stands of species with low resistance

to lateral competition;3.

Avoid conditions with potential for high inoculum build‐up &

vulnerability to stand collapse in the face of fungal pathogens;

Ideal conditions forRed band needle blight

Failure to remove weak spruce ‐

increased risk from impact of

Dendroctinus

infestation


Risk of accumulation of inoculum in

blocks of dense larch & ash

Presenter

Presentation Notes


The Question?

1.

What type of forest

structure will deliver the

greatest resilience?2. How do we build in climate & disease mitigation measures?

3. What target forest structure should we aim for?


1. Lower growing stocks – Aerate the stand &

promote crown development;


2. Target removal of weak trees – those in decline & with poor crowns;3. Promote growth of well‐formed vigorous trees;


4. Maintain the woodland conditions (at the stand level) –

Reduce in‐stand climatic extremes;


5. Harvest the increment, replenishing with desirable species and

develop a vertical structure
